verb; past tense. The act of removing a sitting House Speaker by voting him out of his congressional seat, thus also removing him from the Speakers Chair. Uncommon because Speakers usually gerrymander their seat to be very safe. A de-Foley-ated speaker is an earlier version of a gore-loser.
In the US congressional elections of 1994, George Nethercutt de-Foley-ated then House speaker Tom Foley by beating him in the election.
